  • Applications

    Pindone (CAS 83-26-1) is used as an anticoagulant rodenticide in bait formulations to control rats and mice. In practice, it supports agricultural and stored-product protection by suppressing rodent damage to crops and stored grains, is employed in urban and household pest-control programs, is formulated into professional rodenticide baits for use in food-processing and storage facilities, and may appear in consumer bait stations under local regulations.
